PROCESS OF COATING PAPER AND CLOTH.

SPECIFICATION forming part of Letters Patent No. 226,459, dated April13, 1880.

Application filed October 4, 1879.

To all whom it may concern Be it known that I, AUGUSTINE SAGKETT, of NewYork city, in the county of New York and State-of New York, haveinvented a new and useful Process for Coating Rolls of Paper on oneside, preserving at the same time the reverse side free from the coatingmaterial, of which the following is a specification.

This invention is especially useful where it is desired to coat one sideof the paper with a cement which cannot well be applied with brushes,either on account of its semi-fluid consistency or the necessity ofapplying it at a high degree of heat. This has been done by drawing thepaper under a revolving cylinder, the lower part of which cylinder isimmersed in the coating material, depending upon the close contact ofthe surfaces of the cylinder and paper to prevent the coating materialfrom coating both sides of the paper. Itis difficult to do thiseffectually, and the cylinder and clean side of the paper are liable tobecome, to some extent, covered with the cement.

The object of my invention is to avoid this difficulty.

I accomplish this by wholly immersing the cylinder, which may eitherrevolve or remain stationary, and instead of passing one sheet of thepaper around it I pass two sheets in close contact when they enter thecement, and drawing them up between two rollers or scrapers so adjustedas to remove the superfluous cement just after the paper leaves thesurface of the cement. It will then be found that the cement has notpenetrated between the sheets of paper, but by its weight has pressedthem closely together, thereby keeping one side of each sheet quiteclean, excepting a very narrow margin at the edges.

If it is desired to cement together the two sheets, it may readily bedone by rolling them together as they emerge from the scrapers.

The process can also be employed by only partially immersing thecylinder when it is desired to cement the two sheets together, as thecoated and partially-coated sides will come in contact when rolled up.

My invention is especially applicable in cases Where the coatingmaterial is only semifluid but it will accomplish the purpose wherethere is a high degree of fluidity. It is not confined in itsapplication to paper, but textile fabrics may be coated, provided thecement is of such consistency that it will not penetrate through thefabric.

One Web of cloth and one of paper may also be similarly coated bypassing them together through the coating material.

The coating material may be roofing-pitch or like substance, paste,enamel, coloring material, &c.

In the drawing, A B are rolls of paper; 0, cylinder; D E, scrapers; F,top of cement.

I claim as my invention The process of coating a web or continuous sheetof paper or cloth on one side by passing two sheets or webs of thefabric it is desired to coat through the coating material, having thereverse sides in close contact, substantially as above described.

AUGUSTINE SAOKETT.
